Abstract
Provided is a means for beneficially solving the problems of increasing separator productivity and further improving adhesion between an electrode and a separator in electrolysis solution while ensuring battery characteristics. A composition for non-aqueous secondary battery functional layer is provided that contains non-conductive inorganic particles and organic particles, wherein a difference in density between the non-conductive inorganic particles and the organic particles (non-conductive inorganic particles' density—organic particles' density) is 1.5 g/cmor more, and the organic particles each have a core-shell structure having a core and a shell that partially covers an outer surface of the core, wherein the core is made of polymer having a degree of swelling in electrolysis solution of 5 times to 30 times, and the shell is made of polymer having a degree of swelling in electrolysis solution of greater than 1 time to 4 times.
